https://codereview.chromium.org/283093002 fixed some bugs in pipe memory allocation, but also introduced one of its own: nearly every block requested from needOpBytes() got its own 16K allocation. The correct logic is to take the requested size, add four more bytes for a DrawOp, make sure that's 4-byte aligned, then check to see if there's enough space for that in the current block. If there's not, allocate at least MIN_BLOCK_SIZE bytes to fit the request. The bug is that I moved that round-up-to-MIN_BLOCK_SIZE step before checking for space in the current block. This means most (all?) blocks will be 16K but never seem to have room to fit another allocation. You need 8 bytes? You get 16K. You need 8 more bytes? Nope, can't fit that. Here's a new 16K... This reverts the change to the test I made then, which really should have tipped me off. It was testing exactly this bug.
